Sherlockians generally praise two screen incarnations of Holmes: One is British actor Jeremy Brett's portrayal of the sleuth in TV series from 1984 to 1994, and the other is by Plummer in the 1979 film "Murder by Decree," which costars James Mason as Watson.

To be a “Sherlockian” (in England, a “Holmesian”) is to do more than read Sherlock Holmes with delight; it is to enter a world of trivia questions, films, parodies, interlocking societies, little magazines, T-shirts, nostalgia, and a dedication bordering on mania.
